Wiring The preferred method of bringing input signal in to the amplifier is with RCA

cables from a quality tape or CD player. A high (speaker) level input signal may alsobe used if your factory deck or aftermarket source does not have low level RCA

jacks. It is not recommended to mix high and low level inputs. Engine noise in the

system will probably result.

Some of the system possibilities are shown in the System Diagrams section of

this manual.

When working with power connections always hook up the ground wire firstand disconnect the ground wire last. Never make any wiring changes with the

amplifier powered up.

The chassis mounted fuse(s) are in place to protect the circuitry of the

amplifier in the event of major trouble. An in-line fuse must be installed within 18

inches of the battery to protect the power wire used to supply current to the

amplifier. For the Kicker Impulse IX405D amplifier a fuse value of 60A and 8 gauge

power wire are recommended. If the power wire is longer than 10 feet, we rec-

ommend that the wire size be 4 gauge to reduce losses.

Any time that a power wire goes through a metal panel such as the firewall,

or if there is any chance of abrasion, it is necessary to use a grommet or other

suitable form of protection to avoid shorts.

EXPLANATION OF INPUT OPTIONS FOR THE IMPULSE IX405D

The IX405D amplifier has five different options for hookup to your source unit.

1. One pair of RCA cables.

2. Two pairs of RCA cables.

3. Three pairs of RCA cables.

4. One stereo pair of high level inputs.

5. Two stereo pairs of high level inputs.

The Parallel input selector switch allows you to select one or two inputs (low level or

high). The sub channel gets its signal from the front and rear inputs, or from separate RCA jacks, determined by the position of the Sub Channel input switch.

Input Option 1: Using One Pair of RCA Cables

With the Parallel input selector switch in “ON” position, and the Sub input switch in the

“F+R” position, all five channels receive input from the front input RCA’s.

Input Option 3: Using Three Pairs of RCA Cables

If the source unit has a separate sub output or if using an external crossover,

use this configuration. With the Parallel input selector in the “OFF” position and

RCA’s plugged into the sub inputs, you have six inputs and five channel outputs,

all separate

Input Option 4: Using a Stereo Pair of High Level Inputs

With the Parallel input selector switch in “ON” position, and the Sub input

switch in the “F+R” position, all channels receive input from the front high level

inputs. There is no fader capability.

Basic Sub Options for the KICKER IX405D

Your Kicker Impulse IX405D has a mono/single channel subwoofer output

section . The minimum total load that the subwoofer section will accommodate is

a 2 Ohm load. Four screw terminals are provided for ease of installation when

multiple woofers are being used, but full output can be had by using only one pair

of terminals.

The following diagrams suggest a number of different subwoofer system

possibilities.

Adjustments and Controls

Setting Gain Control

The gain control is provided for level matching purposes. The control doesnot give the amplifier any more power by turning it up. Its purpose is to adjust

the sensitivity of the amplifier in relation to the output level provided by the

source.

Start with the amp gains set to minimum by turning the controls counter-

clockwise. Turn the source level up until distortion is barely audible. Then turn the

source down slightly. This will typically be at about 85 to 95% of full volume. Raisethe front amplifier gain control until distortion is just audible in the front speak-

ers. Now the deck is matched to the front amplifier channels. Turn the source

down to a realistic listening level.

Turn the rear amplifier gain control up until the desired front/rear balance is

achieved.

Turn the remote subwoofer control all the way up. Turn the sub gain adjust-ment on the amplifier chassis up to provide the bass level desired.

Note: As the KICKEQ controls are turned up to provide additional bass or tre-

ble, the overall signal goes up. It may be necessary to readjust the gain controls if

the KICKEQ controls are turned up very much.

Troubleshooting

The LED mounted on the end panel of the amplifier lights up in two different

colors depending on the condition of the amplifier. Green indicates that the

amplifier is turned on and no trouble exists. When it turns red this indicates that

the protection circuit has been engaged. The LED on the top of the amplifier

chassis indicates that the amplifier is on. When the protection circuit is engaged,

this LED turns off.

Green power indicator off, no output:

• With Volt Ohm Meter (VOM) check:1. +12v power terminal

2. Ground terminal

3. Remote turn-on lead

Green power indicator on, no output:

• Check RCA and connections• Test speaker outputs with known good speaker

• Check function of source unit

• With VOM in AC volts position check RCA for signal

No output from one channel:
